| Abstract | The main purpose of this contribution is to increase the knowledge of the geological resources of “Tras-os-Montes e Alto Douro” (TMAD) region, in particular of it “Schist” (slate, phyllite, Schist and quartzite), considering its economic and social impact. The target area is characterized by the abundant occurrence of different types of “Schist”, from the Hercynian basement, belonging to Galiza Tras-os-Montes Zone (GTMZ) and to the Central Iberian Zone (CIZ). The main outcome of this work was to improve the knowledge about mineralogy, fabric, chemistry and technology of the “Schist”, which can promote their exploitation and use as a natural stone. It was possible to identify the main factors that have an influence on the mechanical behaviour of the schists, conditioning their use as natural stone. This work also contributed to increase the knowledge about lithology and it allowed to show how the relationship between the metamorphic grade and the deformation intensity have a great influence on the stone properties and consequently on the type and size of the exploration site. |
